A shoe box has a volume of 64 cubic inches and a
surface area of 160 square inches. What is the surface
area of a similar shoe box if its volume is only 27 cubic inches? Show your work or explain how you got your answer
The surface area of a similar box given the ratio of volume to surface area of first box is 67.5 square inches
How to solve ratio?Box A:
volume = 64 cubic inchesSurface area = 160 square inchesBox B:
volume = 27 cubic inchesSurface area = xVolume : surface area
64 : 160 = 27 : x
64/160 = 27/x
64 × x = 160 × 27
64x = 4,320
x = 67.5 square inches
Therefore, the surface area of a similar box given the ratio of volume to surface area of first box is 67.5 square inches

Estimate:
11 is 50% of what number?
A 20
B 40
C 60
D 5
Answer:
50% of a number means that we are taking half of a number. Since 11 is 50% of a number that means that we need to multiply 11 by 2 to get the original number. When we multiply 11 by 2 we get 22 and that is closest to option A which is 20.

For the region bounded by y=3x, the x-axis, and x=4, determine the volume when
The area bounded by the line y=3x from limits x=0 to x=4 will be 24.
What is integration?
Integration is defined as the adding up all the small units to find the whole unit.
It is given in the question that the line y=3x is making a region in a plane from the limits x= to x=4.
So by integrating the function we will get the area.
[tex]\int\limits^4_0 y=\int\limits^4_0 {3x} \, dx[/tex]
[tex]\int\limits^4_0 y=3 \int\limits^4_0 {x} \, dx[/tex]
[tex]\int\limits^4_0 y=[\dfrac{3x^2}{2}]^4_0[/tex]
[tex]\int\limits^4_0 y= \dfrac{(3\times (4)^2)}{2}[/tex]
[tex]\int\limits^4_0 y= 24[/tex]
hence the region bounded by the line y=3x will have the area of 24 square units.

uhhh what is this this looks very hard
Answer:
B. x ≤ 5
Step-by-step explanation:
This is an inequality problem. It can be solved by examining the arrow and the point it closes on. If the arrow is going left, then all values of x are going to be less than the point it closes on. If the arrow is going right, then all values of x are going to be greater than the point it closes on.
If the circle on the point the arrow is closed/shaded in, then that value will be included in the values of x, giving the inequality either a ≤ or ≥ sign depending on which way the arrow is pointing. If the circle on the point the arrow is open, then that value will not be included in the values of x. The sign will be either < or >.
---------------------------------------------------------------------------
For this problem, the arrow is going to the left of 5, which means all values of x are going to be less than 5. Because the circle is closed, that means that number 5 is included, or x can be equal to 5. If the circle was open, it wouldn't be included. So, the inequality is x ≤ 5.

The circumference of a circle is 24π cm. What is the area, in square centimeters? Express your answer in terms of \piπ.
Given the value of the circumference of the circle, its area in terms of constant pi is 144πcm².
What is a circle?A circle is simply a closed 2-dimensional curved shape with no corners or edges.
The area and circumference of a circle is expressed mathematically as;
A = πr²C = 2πrWhere A is area, C is circumference, r is radius and π is constant pi.
Given the data in the question;
Circumference of the circle C = 24π cmArea A = ?First, we determine the radius of the circle.
24π cm = 2πr
r = 24π cm / 2π
r = 12cm
Now, we find the area.
A = πr²
A = π × (12cm)²
A = π × 144cm²
A = 144πcm²
Therefore, given the value of the circumference of the circle, its area in terms of constant pi is 144πcm².

Galvin and Henry spend a certain amount of money from their money box each month to buy plants. The table (function 1) shows the relationship between the amount of money (y) remaining in Galvin’s money box and the number of months (x): Number of Months (x) Amount Remaining (in $) (y) 1 80 2 75 3 70 4 65 The equation (function 2) shows the relationship between the amount of money, y, remaining in Henry’s money box and the number of months, x: Function 2 y = −7x + 80 Which statement explains which function shows a greater rate of change? Function 2 shows a greater rate of change, because Henry spends $7 each month and Galvin spends $5 each month. Function 2 shows a greater rate of change, because Henry spends $80 each month and Galvin spends $15 each month. Function 1 shows a greater rate of change, because Galvin spends $15 each month and Henry spends $73 each month. Function 1 shows a greater rate of change, because Galvin spends $5 each month and Henry spends −$7 each month.
Answer:
Function 2 shows a greater rate of change, because Edwin spends $9 each month and Adam spends $7 each month.
I found this out because for Adam, you simply subtract the y-coordinates from each other and get 7 each time. Edwin clearly shows that he Spends $9 each month with the negative sign.
Step-by-step explanation:
Answer:
Function 2 shows a greater rate of change, because Henry spends $7 per month and Galvin spends $5 per month.
Step-by-step explanation:
Function 1
Money remaining in Galvin's money box:
[tex]\begin{tabular}{| c | c |}\cline{1-2} Number of Months (x) & Amount Remaining (in \$) (y)\\\cline{1-2} 1 & 80\\\cline{1-2} 2 & 75 \\\cline{1-2} 3 & 70 \\\cline{1-2} 4 & 65 \\\cline{1-2}\end{tabular}[/tex]
We can calculate the rate of change by using this formula:
[tex]\textsf{rate of change}=\dfrac{\textsf{change in y}}{\textsf{change in x}}[/tex]
[tex]\implies \textsf{rate of change}=\dfrac{75-80}{2-1}=\dfrac{-5}{1}=-5[/tex]
Therefore, The rate of change of function 1 is -5 which means that Galvin spends $5 per month.
Function 2
Money remaining in Henry's money box:
[tex]\sf y = -7x+80[/tex]
This is represented as a linear equation: y = mx + b
(where m is the slope or "rate of change" and b is the y-intercept of "initial value)
Therefore, the rate of change of function 2 is -7 which means that Henry spends $7 per month.
Conclusion
Function 2 shows a greater rate of change, because Henry spends $7 per month and Galvin spends $5 per month.

Several students made comments about this image.
A triangle has angles B, C, D. The exterior angle to angle B is A.
Which comment is true?
“If I know the measures of A and B, I can subtract those measures from 180 to find the measures of the other two angles.”
“If I know the measure of C, I can find the measure of angle A because they are the same.”
“If I know the measures of angles C and B, I can find the measures of A and D.”
“If I know the measure of angle A, I can find the measure of angle D by subtracting from 180
Answer:
The third comment is the true one: "If I know the measures of angles C and B, I can find the measures of A and D."
This is because you can use the angle B to find angle A by subtracting it from 180, and you can find angle D by adding together C and B and subtracting that from 180.
